Abstract
The torsional flexible connection has two coaxial flanges or discs equipped with sets of equidistant radially or axially protruding blades which are interdigitated to form a plurality of wedge-shaped chambers whose sides intersect at the axis of the connection, all or some of which receive torque-transmitting flexible inserts which transmit force and rotation to one of the flanges/discs in response to the force and rotation transmitted from the other flange/disc or vice versa. Each insert is comprised of two or several elements of a streamlined shape placed at different distances from the axis, so that the dimensions of these elements in the direction of transmitted payload are proportional to their distances from the axis.
Claims12
A torsional flexible connection for mechanical power transmission comprising:
- an inner hub and an outer hub disposed in a coaxial relationship about a common axis of rotation, each hub including a plurality of wedge shaped blades projecting therefrom, each of said blades being defined by a pair of spaced apart sides which are disposed along radii of said connection passing through said axis of rotation, said blades of said inner hub being disposed in an interdigitating, spaced apart relationship with the blades of the outer hub so that a plurality of wedge shaped chambers are defined therebetween;
- and
- at least two of said chambers including a torque transmitting, flexible insert disposed therein, said flexible insert including at least a first and a second torque transmitting element, disposed in a spaced apart relationship, and lying along a common radius of said connection passing through said axis of rotation, said first element being spaced from said axis by a distance d.sub.1 and having a diameter D.sub.1, said second element being spaced from said axis by a distance d.sub.2 and having a diameter D.sub.2, said elements being configured so that d.sub.1 /D.sub.1 =d.sub.2 /D.sub.2 ;
- whereby said first and second elements experience the same degree of relative compressional deformation when torque is transmitted between said inner hub and said outer hub.
